CONEA-PULLEY STRUCTURE.

SPECIFICATION forming partl of Letters IPatent No. 739,368, dated September 22, 1903. Application filed November l0, 1902. Serial No. 130,721. (No model.)

To alli/177.0711, it may concern:

Be it known that we, HENRY P. WHITE and LEWIS E. PAYuE,citizens of the United States,

residing at the city of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Cone -Pulley Structures, of which the following is a specification.

This invention relates to improvements in cone-pulley structures.

The invention is particularly applicable to speed-regulators of the belt-driven cone-pul ley type, such as are described and illustrated in the United States Let-ters Patent to Henry P. White, issued'June 24, 1902,No. 703,027, in which the belt is arranged and guided so that its like edges are presented to the corresponding ends of the cone-pulleys; and the invention is illustrated in connection with a machine of that class, although it is adapted for use in other relations.

The objects of the invention are, rst, to

' provide an improved belt-driven cone-pulley structure by which any compensating slip of the belt is prevented; second, to provide an improved idler for belts for use in connection with cone-pulleys which in operation Willcause the belt to closely and properly fit upon the cone-pulleys and idlers at every point of its contactsurface. Y Y

Further objects willdetinitely appear in the detailed description to follow.

l The objects of this invention are accomplished by the devices and means described in this specification.

The invention is clearly defined and pointed out in the claim. A f

A structure embodying the features of this invention is fully illustrated in the accompanying drawings, forming a part of this specification, in which` Figure l is a side elevation View of a structure embodying the'features of out` invention. Fig. 2 is an end elevation View looking from theleft of Fig. 1 with the pulleysb removed. Fig. 3.is' an enlarged detail view showing the structure of one of our idlers, one of said idlers being shown in section on a line corresponding to line 3 3 of Fig. l looking in the direction of the little arrows.

In the drawings similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, the various parts are supported on a 55 suitable frame A. The driven cone B is mounted upon a suitable shaft, which also carries the tight and loose pulleys b, which represent the medium through which power may be delivered' to the machine. "A driv- 6o` ing-cone B is mounted upon a suitableshaft which is supported at an angle, preferably at right angles, to the shaft of "the driven cone B. The cones B B'. arel arranged so that their like ends occupy the same relative positionsV toward a common meeting-point of the shafts. f

The track or WayA' is supported by the frame A. A carriage C is adapted to reciprocate along this track, and suitable means 7o are provided for moving it thereon. Onthe axle or shaft C', carried by the carriage C, are idlers D, whichare adapted to support and guide the connecting-belt B of said cone. The idlers D are cone-shaped and are formed of sections d, independently revoluble on the hub c of the idler, which is adapted to revolve onA the axle C.

In a speed-regulatorof the class described when belts ofany considerable width are 8c `used itV is found quite necessary to shape them to thepulleys, as the same edge is always presented to the like ends of the pulleys.

pendently, and the belt is'guided and presented to the cone in the proper position to reduce the strain thereon to a minimum. By the use of our improved cone-pulley structure loo In passing over the guide-pulley or idler of in this relation it is found entirely practical to use a straight belt-that is, a belt without any special shaping, as is otherwise desirable.

We have illustrated and described our im proved cone-pulley structure in connection with a speed-regulator. We are aware, however, that it has very great advantages for use in other relations, and therefore desire to claim the same specifically in combination with a speed-regulator, as well as broadly.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

The combination of a plurality of independently-revoluble sections of uniformlyincreas- Ving diameters, which together unite to form an idler of regular taper, as specified.

In testimony whereof we have hereunto set our hands and seals in the presence of two Witnesses.
